Re: using keyword problem

[Eljay Love-Jensen <eljay@adobe.com>]

Hi Artur,

The "using" keyword is for bring identifiers from one namespace available 
in the current namespace.

For example:
using std::cout; // cout is now accessible, without the std:: qualifier.
using namespace std: // the whole std:: uberverse is accessible.  Avoid 
collisions!

A class and a struct or sort of like namespaces, and also not like namespaces.

You want to do this...

class A
{
public:
     struct S
     {
         int x;
     };
};

int Method()
{
     typedef A::S S; // using A::S is no good here.

     S s;
     s.x = 1;
     return s.x;
};

HTH,
